Effects of bodyweight neuromuscular training with and without instability on balance control in active universitarians

The purpose of this study was to analyse the effects of a nine-week unstable vs stable bodyweight neuromuscular training programme on balance control. Seventy-seven physically active universitarians were randomly distributed into an unstable training group (UTG), a stable training group (STG), and a control group (CG). The intervention was conducted three times a week for nine weeks. Pre- and post-intervention assessments included static balance control under an unstable surface (eyes open (EOFS), eyes closed (ECFS), challenging visual-vestibular system (CVVS)), assessed as centre-of pressure fluctuations with a force plate. A mixed ANOVA was performed to test the within- and between-subjects factors. After the intervention, no significant differences were found between groups. All groups presented significant improvements in balance measurements in EOFS (p = 0.01), ECFS (p = 0.01; p = 0.02), and CVVS (p = 0.01) conditions. The training groups tended to have significantly better balance control (antero-posterior) than the CG on EOFS. In the CVVS condition, the UTG tended to have better balance control than the CG. There was no overall significant train ing advantage gained by using unstable or stable surfaces in terms of the improvement in static balance control in active universitar ians. Both training groups exhibited similar training adaptations.D915-7373-ED16 | Cesar LeaoN/

The relationship between static and dynamic balance in active young adults

Purpose. The objectives were to analyse differences of static and dynamic balance between sexes and test the correlations between static and dynamic balance measures. Methods. The study involved 77 physically active adults, university students (age: 19.1 ? 1.1 years; height: 170.2 ? 9.2 cm; body mass: 64.1 ? 10.7 kg). Static balance was assessed with a force platform under Romberg conditions: a foam surface, eyes open (EOFS); eyes closed (ECFS); challenging the visual-vestibular system (CVVS). The Y Balance Test (YBT) evaluated dynamic balance in anterior, posteromedial, and posterolateral directions. One-way ANOVA examined potential differences between sexes, and the Pearson product-moment test verified the correlations between YBT and static balance measures. Results. Sex differences were found for all conditions in static balance variables: ellipse area (EA), centre of pressure displacement anteroposterior (DAP) and mediolateral (DML), mean velocity anteroposterior (VAP) and mediolateral (VML), total mean velocity (TV). Females presented a better stability index than males for EOFS (25% DAP, 20% DML, 30% VAP, 21% VML, 19% TV), ECFS (26% DAP, 32% DML, 28% VAP, 32% VML, 32% TV), and CVVS (27% EA, 26% DAP, 19% DML, 17% VAP, 20% VML, 18% TV). Males demonstrated 6% better performance on YBT posterolateral. Correlation tests revealed small to moderate correlations between static and dynamic balance, except for a large positive correlation between YBT anterior and sway area under the CVVS condition [r = 0.54 (0.19; 0.77)] for women. Conclusions. The findings indicate a weak relationship between static and dynamic balance in controlling posture.D915-7373-ED16 | Cesar LeaoN/

O delineamento utilizado foi inteiramente casualizado, em esquema fatorial triplo 2x2x8 (duas popula\ue7\uf5es da esp\ue9cie; dois est\ue1dios de crescimento \u2013 regenerante e adulto; e oito tratamentos de controle), com 10 repeti\ue7\uf5es. Os tratamentos testados foram: testemunha; anelamento do caule; anelamento e pincelamento do caule com \uf3leo lubrificante usado; anelamento do caule e aplica\ue7\ue3o de 2,4-D + picloram; corte raso; corte raso seguido de queima das cepas; corte raso e pincelamento de \uf3leo lubrificante usado nas cepas; e corte raso e aplica\ue7\ue3o de 2,4-D + picloram nas cepas. No total foram monitorados 320 indiv\uedduos, dentre estes, 160 regenerantes e 160 adultos. As vari\ue1veis avaliadas foram: porcentagem de controle; n\ufamero de brota\ue7\uf5es; di\ue2metro e comprimento de brota\ue7\uf5es. Dentre os tratamentos avaliados, os que se mostraram mais eficientes no controle de Prosopis juliflora foram o corte raso, seguido de queima das cepas e aplica\ue7\ue3o de 2,4-D + picloram em plantas cortadas e aneladas. O pincelamento de \uf3leo lubrificante na base de plantas aneladas tamb\ue9m se mostrou uma estrat\ue9gia promissora no controle da invasora.The objective of this study was to evaluate the efficiency of different methods to control Prosopis juliflora , invasive alien species in the semiarid region of northeastern Brazil. The experimental design was completely randomized in triple factorial scheme 2x2x8 (two populations of the species, two growth stages - regenerating and adult individuals and eight control treatments), with 10 repetitions. The treatments were: control, girdling of the stem, girdling and brushing of used lubricating oil; girdling and application of 2,4-D + picloram, clear cutting, clear cutting followed by burning of the stump; clear cutting and brushing of used lubricating oil; and clear cutting and application of 2,4-D + picloram. In total 320 individuals were monitored, among these, 160 regenerates and 160 adults individuals. The variables evaluated were: percentage of control, number of shoots, diameter and length of shoots. According to the results among the treatments, those who were more effective in controlling Prosopis juliflora were clear cutting followed by burning of the stump and application of 2,4-D + picloram in cut and girdled plants. The brushing lubricating oil on the basis of girdled plants also showed a promising strategy to control invasive

Effect of ultraviolet radiation on the color of freij\uf3 wood ( Cordia goeldiana Huber) after application of finishing products

A radia\ue7\ue3o ultravioleta \ue9 considerada a mais prejudicial ao uso da madeira afetando suas propriedades, sobretudo a sua cor superficial. A aplica\ue7\ue3o de produtos de acabamentos, como os vernizes, os stains, as tintas, podem minimizar a atua\ue7\ue3o dessa radia\ue7\ue3o. Este trabalho teve como objetivo avaliar o efeito da radia\ue7\ue3o ultravioleta, relativo ao envelhecimento artificial acelerado, na colora\ue7\ue3o da madeira de freij\uf3 ( Cordia goeldiana Huber) tratadas com polisten e seladora (nitrocelulose), com monitoramento por meio de um espectrocolorimetrico. As amostras da madeira foram submetidas a ciclos de radia\ue7\ue3o ultravioleta em um reator fotoqu\uedmico, em tempos de 84 e 168 horas. Os par\ue2metros colorim\ue9tricos (L*, a*, b* C e h*) foram medidos antes a ap\uf3s os tratamentos. O tratamento com polisten foi o que ofereceu maior prote\ue7\ue3o \ue0s radia\ue7\uf5es ultravioletas, dando uma maior estabilidade aos par\ue2metros. O tratamento com seladora foi o que apresentou uma maior altera\ue7\ue3o da cor ap\uf3s a simula\ue7\ue3o de envelhecimento no reator fotoqu\uedmico.Ultraviolet radiation is considered the most damaging radiation to wood, affecting its properties and especially its color. The application of finishing products such as varnishes, stains and inks can minimize the action of this radiation. This study aimed to evaluate the effect of ultraviolet radiation, through artificially accelerated aging, on the color of freij\uf3 wood ( Cordia goeldiana Huber) treated with \u201cpolisten\u201d and sealer (nitrocellulose), by means of spectrocolorimetric tracking. The samples of wood were subjected to cycles of ultraviolet radiation in a photochemical reactor for 84 and 168 hours. The colorimetric parameters (L*, a*, b*, C, h*) were measured before and after the treatments. The treatment with \u201cpolisten\u201d offered greater protection against ultraviolet radiation, yielding greater stability to the parameters. The treatment with sealer led to a greater change in color after the simulation of aging in the photochemical reactor

Chimerical dataset creation protocol based on Doddington Zoo : a biometric application with face, eye, and ECG.

Multimodal systems are a workaround to enhance the robustness and effectiveness of biometric systems. A proper multimodal dataset is of the utmost importance to build such systems. The literature presents some multimodal datasets, although, to the best of our knowledge, there are no previous studies combining face, iris/eye, and vital signals such as the Electrocardiogram (ECG). Moreover, there is no methodology to guide the construction and evaluation of a chimeric dataset. Taking that fact into account, we propose to create a chimeric dataset from three modalities in this work: ECG, eye, and face. Based on the Doddington Zoo criteria, we also propose a generic and systematic protocol imposing constraints for the creation of homogeneous chimeric individuals, which allow us to perform a fair and reproducible benchmark. Moreover, we have proposed a multimodal approach for these modalities based on state-of-the-art deep representations built by convolutional neural networks. We conduct the experiments in the open-world verification mode and on two different scenarios (intra-session and inter-session), using three modalities from two datasets: CYBHi (ECG) and FRGC (eye and face). Our multimodal approach achieves impressive decidability of 7.20 ? 0.18, yielding an almost perfect verification system (i.e., Equal Error Rate (EER) of 0.20% ? 0.06) on the intra-session scenario with unknown data. On the inter-session scenario, we achieve a decidability of 7.78 ? 0.78 and an EER of 0.06% ? 0.06. In summary, these figures represent a gain of over 28% in decidability and a reduction over 11% of the EER on the intra-session scenario for unknown data compared to the best-known unimodal approach. Besides, we achieve an improvement greater than 22% in decidability and an EER reduction over 6% in the inter-session scenario

Nutrition status and quantification of blood minerals by TXRF spectroscopy in vegetarian and non-vegetarian university students.

This study investigated whether university students following a vegetarian diet differed from non-vegetarian students in nutrient intake, biochemical, hematological and blood mineral profile of nutritionally relevant elements. In total, 107 students from a university, following either a non-vegetarian or a vegetarian diet for at least 1 year prior to the study, were recruited in two stages, setting up two experiments. Nutrient intake (experiment 1, n = 58), and biochemical and hematological parameters (experiment 2, n = 49) were evaluated. TXRF spectroscopy was used for determination of trace elements in whole blood. Vegetarians showed differences in nutrient intake, mainly higher consumption of unsaturated fatty acids and fiber. No significant differences in the biochemical and hematological parameters were found. The prevalence of abnormal parameters in a considerable number of vegetarians and non-vegetarians were found, mainly regarding high density lipoprotein (HDL-c) and total cholesterol (TC). TXRF spectroscopy proved to be a simple tool for determining nutrition-relevant elements (K, Fe, Cu and Zn) in blood samples. The high incidence of abnormal parameters, regardless of the dietary pattern, raises concern about the high prevalence of bad eating habits among young university students. Particularly for the vegetarian students, these results may partly counteract the beneficial lifestyle of a vegetarian diet evidenced by previous studies. It is important for students to be aware of its potential nutritional limitations. In this context, food and nutrition education programs in the academic context could contribute to set up autonomous and healthy subjects, regardless of the diet chosen

Effect of cooking method on the formation of 7-ketocholesterol in Atlantic hake (Merluccius hubbsi) and smooth weakfish (Cynoscion leiarchus) fillets.

The levels of cholesterol and 7-ketocholesterol were measured in raw Atlantic hake (Merluccius hubbsi) and smooth weakfish (Cynoscion leiarchus) fillets and in fillets subjected to the following cooking methods: baking in an electric or microwave oven; baking, grilling or stewing in a steam-convection oven; simmering on a stove; electric grilling; and deep frying. The raw samples from both fishes exhibited significantly (p < 0.05) higher cholesterol levels (62.71 ? 6.06 mg/100 ge74.16 ? 3.96 mg/ 100 g) than the processed fillets. In all of the samples, 7-ketocholesterol was detected at significantly (p < 0.05) different levels depending on the cooking method and the type of fish. Steam cooking keeping the surface of the product moist produced small decrease in the cholesterol content (26.65%e29.96%) and a low level of 7-ketocholesterol in the samples (6.90 ? 0.21 mg/ge6.47 ? 0.28 mg/g). Baking in electric or steam-convection ovens at high temperatures and long times greatly reduced the cholesterol content (52.77%e65.08%), which was associated with a large increase in 7-ketocholesterol levels (11.54 ? 0.45 mg/ge13.94 ? 1.17 mg/g). These results indicate the necessity of revising the baking procedures for fish to increase the healthiness of food

nutrition and performance in football

Nutrition is an undeniable part of promoting health and performance among football (soccer) players. Nevertheless, nutritional strategies adopted in elite football can vary significantly depending on culture, habit and practical constraints and might not always be supported by scientific evidence. Therefore, a group of 28 Portuguese experts on sports nutrition, sports science and sports medicine sought to discuss current practices in the elite football landscape and review the existing evidence on nutritional strategies to be applied when supporting football players. Starting from understanding football?s physical and physiological demands, five different moments were identified: preparing to play, match-day, recovery after matches, between matches and during injury or rehabilitation periods. When applicable, specificities of nutritional support to young athletes and female players were also addressed. The result is a set of practical recommendations that gathered consensus among involved experts, highlighting carbohydrates periodisation, hydration and conscious use of dietary supplements.D915-7373-ED16 | Cesar LeaoN/
